Consider the quadratic equation x^2 +7x+8=0. Which of the following is the correct form after substituting a, b, and c into the
Quadratic Formula?
Answer:
ax²+bx+c=0
Being the standard formula
Step-by-step explanation:
By direct substitution
a=1
b=7
c=8
If the quadratic equation x² +7x+8=0 then the correct form after substituting a, b, and c into the Quadratic Formula is x=-7±√7²-4(1)(8)/2(1)
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given quadratic equation is x² +7x+8=0.
The quadratic equation standard form is ax²+bx+c=0
When we compare both the equations
The value of a is 1, b is 7 and c is 8
x=-b±√b²-4ac/2a
x=-7±√7²-4(1)(8)/2(1)
=-7±√49-32/2
x=-7±√17/2
Hence, if the quadratic equation x² +7x+8=0 then the correct form after substituting a, b, and c into the Quadratic Formula is x=-7±√7²-4(1)(8)/2(1)

coterminal angles
HELP what is the coterminal angle for -230° in the range of (0,360°)
Answer:
The coterminal angle of -230º is 130º.
Step-by-step explanation:
Coterminal angles are those whose sides start and end at the same point, therefore sharing a common side. To obtain the coterminal angle of a negative angle, 360º must be added to the value of said negative angle. Therefore, the coterminal angle of -230º arises from the following calculation:
-230 + 360 = X
130 = X
Therefore, the coterminal angle of -230º is 130º.

Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as Hernando and Rachel's solution are not provided. So, I will just solve the question directly.
Given
[tex]2mp-6p+27-9m[/tex]
Required
Factor
[tex]2mp-6p+27-9m[/tex]
Group into 2
[tex]2mp-6p+27-9m = [2mp-6p]+[27-9m][/tex]
Factor each group
[tex]2mp-6p+27-9m = 2p[m-3]+9[3-m][/tex]
Rewrite 3 - m as -(m-3)
So, we have:
[tex]2mp-6p+27-9m = 2p[m-3]-9[m-3][/tex]
Factor out m - 3
[tex]2mp-6p+27-9m = [2p-9][m-3][/tex]
In circle R with QRS=90 and QR= 3 units find the length of arc QS round to the nearest hundredth
Hello, I Am BrotherEye
Answer:
27.92 units
Step-by-step explanation:
Radius (qr) = r = 16 units
<QŘS = θ = 82°
Length of an arc = (Θ / 360) * 2πr
L = (θ / 360) *2πr
L = (82 / 360) * 2π * 16
L = 0.2777 * 100.53
L = 27.917 units
L = 27.92 unit

Answer:
Leg a = 2.6 mi
Leg b = 3.2 mi
No, the biologist will not hike more than 5 mi.
Step-by-step explanation:
The legs of the figure are the two shorter sides. So, the legs on this triangle are 2.6 mi and 3.2 mi long.
To find the hypotenuse, we can use this formula, with c being the length of the route the biologist will take.
a² + b² = c²
We can already plug in the values for a and b.
2.6² + 3.2² = c²
This can simplify to-
6.76 + 10.24 = c²
17 = c²
Now, find the square root of 17 and c² to find the value of c.
[tex]\sqrt{17}[/tex] = [tex]\sqrt{c^{2} }[/tex]
4.1 = c
The hypotenuse is 4.1 mi long.
4.1 > 5, so the answer is no.
Good luck ^^

Answer: look at the picture
Step-by-step explanation: Hope this help :D
The polynomial (8x³ + 12x) / 2x is equivalent to expression 4x² + 6. Then the correct option is A.
What is an equivalent expression?The equivalent is the expression that is in different forms but is equal to the same value.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ (8x³ + 12x) / 2x
Simplify the expression, then we have
⇒ (8x³ + 12x) / 2x
⇒ 4x(2x² + 3) / 2x
⇒ 2 (2x² + 3)
⇒ 4x² + 6
The polynomial (8x³ + 12x) / 2x is equivalent to expression 4x² + 6. Then the correct option is A.

Step-by-step explanation:
This is a simple exponential function (or arithmetic sequence) of
f(x) = 23(2)^x
Since this is fraction 5, x = 5
f(5) = 23(2)^5
f(5) = 23(32)

Write an equation of the line below
Answer:
y = 4/5x - 2
Step-by-step explanation:
To create an equation with just a line compare two points on the graph and see how far the x and y points are on the graph then put them into a fraction with y over x then find the y intercept or find where the x coordinate equals 0 in this case it was (0, -2). Now put it all together:
y = mx + b
mx = comparison of two points
b = y intercept
A shirt originally cost $41.10, but it is on sale for $36.99. What is the percentage decrease of the price of the shirt? If necessary, round to the nearest percent. A. 10% B. 90% C. 11% D. 8%
Answer:
10%
Step-by-step explanation:
The first step is to calculate the decrease
Original price= $41.10
New price= $36.99
= 41.10-36.99
= 4.11
4.11/41.10 × 100
= 0.1×100
= 10%
Hence the percentage decrease is 10%

Trigonometry, can anybody help??
Answer:
angle B: 39
AC: 7.288
AB: 11.58
(note: you cut off the part about rounding so make sure that it's rounded correctly before you put in your answer)
Step-by-step explanation:
To solve this we will use SOH, CAH, TOA
we have the angle and the one opposite to it which means we can use either SOH or TOA
let's use TOA
tan(51)=(9/x)
x= 7.288
We can now use pahtagaryous theroem to solve for the hyptonouse
we have
9²+7.288²=C²
C=11.58
Finally, to find angle B we will recall that the angles of a triangle must add to 180.
51+90+a=180
a=39

The bases in a softball diamond are located at the corners of a 3600 ft^2 square. How far is a throw from second base to home plate
Answer:
84.85 ft
Step-by-step explanation:
Given that the sides are 3600 feets
Hence, side 1 = 3600 ; side = 3600 (since it is a square)
The distance, d from second base to Home plate is the length of the diagonal, which can be obtained using Pythagoras :
d² = s1² + s2²
s1², s2² = 3600
Hence,
d = sqrt(3600 +. 3600)
d = sqrt(7200)
d = 84.85 ft
